| Summary: | -based, fast-response, multi-sensor pressure probes of accurate predictions of the velocity magnitude and algorithm is able to reduce data from any 5- or 7-hole also discussed. A new type of pressure sensor has been and experimental approaches are employed to develop and viscosity. The algorithm utilizes a local least- applications in unsteady and turbulent flow gelds is been calibrated at NASA Langley Flow Modeling and calibration data from miniature non-nulling multi-hole calibration techniques suitable for highly unsteady characteristic size of only 250 gm. These pressure Control Branch for the entire subsonic regime. Each of degrees and maximum errors in velocity prediction less developed with silicon-nitride diaphragm and a development of Micro Electro Mechanical Systems (MEMS) direction, total and static pressure, Mach and Excellent prediction capabilities are demonstrated flow environments with strong spatial gradients. frequency response up to 100 kl-lz. Both computational miniature size for velocity and pressure measurement obtaining a probe bandwidth and a theoretical probe in a subsonic flow field and generate very probes in compressible, subsonic flow gelds. The reduction algorithm for multi-hole pressure probes. Reynolds member and fluid properties like the density sensors are small enough to be mounted close to the squares modeling technique and has been surface of a miniature hemispherical-tip probe, tested on 4 novel miniature 7-hole probes that have than 1%, both with 99 percent confidence. The The algorithm has been developed for the reduction of the probes had a conical tip with diameter of 0.065''. This thesis presents the development of a data crographics. with maximum errors in angle prediction less than 0.6 |
